I am 39. I have regular 24/25 day periods, but nothing since nov23. Tested 24/12 & 31/12 -neg. Any advice?

We've been ttc for 3 months -so I was a bit sad whe ntests came back neg. I'm worried to test again for fear that I am not pregnant, have something wrong with me, have hit early menopause... I live abroad so the medical centres are not exactly friendly and tests are not easy to come by - please give me some advice if you have any... I'm also worried because after testing neg I had wuite a bit to srink over xmas and new year...
